Not really, on a route that long you ideally want at least a decent chunk of layover at the end (I'd say at least 5 minutes). Sending it to Seaham and back gives it essentially no layover, while increasing opportunity for disruption.
To be honest, 15 minutes to Seaham and back would be tight in a car if you encounter even a small amount of traffic. In a bus, with stopping, it would be virtually impossible. So you'd be looking at a PVR increase.
